A proximal tibial osteotomy often results in which of the following?
    • Patellar instability
    • A high tibial osteotomy generally does not lead patellar instability 
    • Reduced survivorship of subsequent total knee arthoplasty (TKA) at 7 years
    • Evidence suggests that TKA survivorship is not reduced at 7 years following a tibial osteotomy 
    • Poor outcomes in patients at 10 years 
    • There are data to support good outcomes following a high tibial osteotomy at 10 years
    • Patella baja
    • A medial opening wedge high tibial osteotomy will pause patella baja
